Signs Your Trailer Bearings Need Replacing
- Replace or service the bearings if you notice rumbling or grinding from the wheels, excessive hub movement, overheating hubs, roughness when rotating the wheel, contaminated or rusty grease, damaged seals, visible bearing corrosion or pitting. For boat trailers, bearings should be inspected regularly because repeated immersion can allow water into the hub and contaminate the bearing grease.
